+1 on EL DAC II performance lack unfortunately. Even the $90 D10 performs similarly it seems. (I do have a D10. It is sensitive to noise - cable and PS quality - but once sorted out, is fine.)
Question OP: What is upstream? Windows PC? Or an 'android box' or? As the LG V20 Quad DAC beats them both.. (Have one. Ordered a second. Unbeatable NIB for $120)
